Though it’s made of soft aluminum and doesn’t hold up very well. I would recommend an EBC brand clutch basket holder or the Suzuki tool for holding the gear on the end of your crankshaft. **Q: Will this work on a Grom?** A: It will work on anything with gears that you need to lock up but not damage. Holds the gears so you can loosen a nut or bolt. **Q: Does this work on Harley touring models?** A: Depends what your exactly trying to jam. Primary? I think so **Q: will this work on my 2000 RM80? i would be using it to remove my primary drive gear.** A: Yes, it works great for that and it's a tough little tool. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great product *by J***E on 10 October 2025* Motion Pro always makes great products ### ⭐⭐⭐⭐⭐ Really handy when torquing nuts and bolts *by J***E on 16 June 2024* I got this when I was rebuilding my dirt bike engine.
